1 Claim. (Cl. 4-109) This invention relates to urinals and has reference more particularly to urinals of the larger sizes, fabricated of pro-formed sheet metal members, and equipped with connections for a continuous or periodic wash down flushing operation.

It is the principal object of the present invention to provide a urinal of the above stated character thatembodies novel features whereby it will be kept in sanitary condition; whereby it is rendered odorless; whereby its drainage facilities are greatly improved and which include a novel form of catch trap for such things as matches, cigar and cigarette butts, paper scraps, etc. which trap can be easily and readily removed for emptymg.

Still further objects and advantages of the invention reside in the particular arrangement and combination of parts employed in the provision of a urinal having the above mentioned features.

In accomplishing the above mentioned and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings wherein:

Fig. 1 is a perspective view of a sheet metal urinal embodying the improvements of the present invention therein.

Fig. 2 is a vertical section through the urinal, taken in the plane of the line 2-2 in Fig. 1.

Fig. 3 is an enlarged, sectional detail taken on line 3-3 in Fig. 2.

Fig. 4 is a vertical section taken longitudinally of the urinal and through the drainage sump and trap.

Fig. 5 is a horizontal sectional detail, taken on the line 5-5 in Fig. 4 showing the arrangement of ozone and ultra-violet light producing lamps.

Fig. 6 is a perspective view showing the drainage sump and parts of the trap as lifted therefrom and separated from each other for better illustration of details.

Referring more in detail to the drawings:

The urinal embodied by this invention is fabricated from sheet metal parts, preferably of stainless steel or other suitable rust proof metal. It comprises a substantially vertical back Wall forming section v10, opposite end wall forming sections 11-11, a bottom section 12 that is disposed substantially in a horizontal plane, and a front or forward wall section 13 that extends upwardly and forwardly from the forward edge of said bottom section.

As will best be understood by reference to Fig. 2, the back wall section 10, and the front wall section 13 are joined to the bottom section in rounded bends, as at :14 and 15, and the forward wall 13, which extends to a height approximately one-third that of the back wall, terminating at its top edge in a forwardly and downwardly curled flange 16; this latter giving rigidity and stiffness to the wall.

The opposite end wall forming sections 11-11 have their lower horizontal edges formed with inwardly and Patented May- 16, 1961 2 upwardly bent flanges 17, as shown in Fig. 4, providing upwardly opening channels within which downturned flanges 18 at the opposite ends of the bottom section 12 are fitted. Also, along their rear vertical edges they are formed with out-turned flanges III to give stiffness and strength thereto.

At its opposite side edges the back wall forming section 10 is formed with back turned flanges 20-20 as shown in Figs. 2 and 5, and these abut flatly against and are welded to the inside surfaces of the rear edge portions of the sidewall members 11-11. It is noted in Fig. 5 that the back wall 10 is set slightly forwardly of the rear vertical edges of the sidewall sections.

The back wallsection 10 is fixed, along its top edge portion to a cross-beam 25 of upwardly opening, channel form as shown in Fig. 2; this cross-beam being located at the back side of the wall and also is fixed at its ends to the sidewall sections 11-11. Across its top the urinal is fitted with a cap or closure plate 26 that has a flat, horizontal portion 26a fixed to the cross-beam 25' over the open top side thereof, and a downwardly sloping forward portion 26b extending between the opposite end walls. This plate 26 is crimped downwardly at its opposite ends, as at 26c in Figs. 1 and 4, over the top edges of the sidewall sections. The front part 26b of cap 26 terminates at its lower edge in an inturned flange 26; which gives stiffness and rigidity thereto.

As will be understood best by reference to Fig. 2, the relationship of parts 10, 12 and 13 is such as to form a trough of substantial depth and width. The back wall section of this urinal as presently being made, is approximately three feet high; the front wall is about one foot high and its top edge is about one foot forward of the back wall.

The bottom wall section 12 is sloped slightly downward from its opposite ends toward a center point as shown in Fig. 4 for better drainage, and it is equipped at the center in its longitudinal direction, with an oblong opening 30 opening into a sump 31. The sump is of sheet metal and its bottom wall is equipped with a fitting 32 for connection with a drain pipe.

Mounted horizontally in the upper part of the urinal and adjacent the back wall section 10, is a water pipe 40. This extends horizontally to the full width of the urinal and is capped or otherwise closed at one end. At its other end, the pipe extends through the end wall 11 and is there adapted and threaded for connection with a water supply pipe. The pipe 40 is formed at close spacing therealong with small discharge orifices 42, as shown in Fig. 3 for downward discharge of water against the back wall 10 as a washdown operation to flush all substances received in the trough into the sump 31. The flow of water can be regulated by certain attachments, not herein shown, made to pipe 40 at the outside of wall 11.

In order to provide for easy cleanout of materials, such as matches, cigar or cigarette butts etc., washed into the sump, it is fitted with a basket 50 as shown in Figs. 4 and 6. This basket has its walls slightly spaced from the walls of the sump and adequately perforated as shown at '55. The basket also has a central cross-member 56 serving as a handle for lifting it from the sump for emptying.

A cover 57 is supported over the sump and basket as shown in Fig. 4, being supported with clearance thereabove and above bottom 12 by legs 58 at its four corners.

For deoderizing purposes, the urinal is equipped within its top portion at opposite sides, as observed in Fig. 5, with electrically operated ozone producing lamps 60-60 and between these there is located a tubular germicidal lamp 61 for producing ultra violet light rays for killing odor producing bacteria. These parts being electrically energized through suitable connections with an electric circuit not shown. Connection in this instance is efiected by use of the usual extension cord 63 shown in Fig. 2.

Urinals constructed in the manner described and illust-rated are -stu'rdy,'1ight in Weight, long lasting, "sanitary and odorless. They may be made in various proportions without departing from the spirit of the invention.

What I claim as new is:

A urinal comprising a substantially vertically extending back wall of substantial height, a bottom wall extending forwardly from said back wall, opposite end walls extending forwardly of said back wall and throughout substantially the full height of the back wall, a front wall extending upwardly from the front edge of said bottom and sloping upwardly and away from said back wall, a cap extending forwardly of the top portion of said back wall and including a portion extending forwardly and downwardly of said back wall, said front wall being of substantially less height than said back wall and said cap extending downwardly only a minor portion of the height of said back wall so as to define an opening of substantial height between said front wall and said cap across the front of the urinal, a substantially horizontally extending wash-down water pipe supported adjacent said back wall at an intermediate portion thereof and having a plurality of perforations formed therein so located as to discharge water therefrom against the back wall in a downward direction, an ultra violet lamp supported adjacent the top portion of said back wall and disposed above said water pipe such that the rays from the ultra violet lamp are distributed throughout the interior of the urinal, ozone producing lamp means supported adjacent the upper portion of said back wall above said water pipe whereby the rays from the lamp means shine directly on the water flowing from the pipe, said ultra violet lamp and said ozone producing lamp means being disposed above the lower edge of said cap so as to be normally hidden from view, said bottom wall sloping slightly downwardly from its opposite ends to a center portion thereof and having an opening formed through the center portion thereof, a sump supported adjacent the under surface of said bottom wall beneath said opening to receive substances passing through said opening, an open-topped catch basket being removably fitted within said sump and having perforations formed through the walls thereof, and a roof-like cover plate having legs fixed to the corner portions thereof and extending downwardly into engagement with the basket to support the cover plate in operative position such that the cover plate is spaced above said bottom wall, the bounding edges of said cover plate extending beyond the edges of said opening in the bottom wall such thatdebris collectedin said sump is normally hidden from view.
